Liquid Silicone Rubber Injection Molding
With extensive experience in liquid silicone rubber injection molding services, Tayang offers an array of custom LSR products, including silicone rubber domes, keypads, housings, etc. From samples to mass production, all tools and silicone rubber products are manufactured in our own facilities. We evaluate the applicability of LSR to the parts you need, whether they are applied in consumer electronics, automotive, medical, etc.
- Less scrap
- Less remaining flash on parting line
- Shorter LSR molding cycle time that can be measured in seconds as opposed to minutes for plastics.
- Preventing contamination from the environment by premixing LSR in a closed system.
- Molding smaller, complex and tight tolerance parts: by flow properties of LSR
- Ability to over-mold LSR onto thermoplastic, metal, magnesium, PCB, FPC and other materials.
- PROPERTIES OF LSR PARTS
LSR’s specific material properties are a result of its unique chemical structure. Its backbone is formed by a series of siloxane bonds which, compared to carbon bonds, are stronger and more stable. This provides liquid silicone rubber products with:
Superior temperature range performance. Liquid silicone products have a wide temperature range. They won’t elongate at high temperatures. They also remain flexible at temperatures as low as -40˚C. High thermal stability makes LSR parts suitable for heavy-duty applications.
Chemical stability. Liquid silicone rubber parts are chemically inert, hypoallergenic and resistant to bacteria growth. They also feature high biocompatibility, which makes them suitable for healthcare applications. However, they can degrade when exposed to certain organic compounds, or to highly acidic or basic environments.
Electrical resistance. On its own, LSR offers high resistance to corona discharge, making it a good choice for use as an insulator in high-voltage applications. However, it is also possible to add conductive materials without compromising the other properties of an LSR component, so that it can be used to make keyboard contact points and other electrical parts.
Liquid silicone rubber molded parts are odorless and tasteless. Unique colors and visual effects can be achieved through the use of pigments and master-batches. Parts are also ozone and UV safe. Other notable features of liquid silicone rubber parts include:
- Resistance to steam and humidity
- Flame retardancy
- Low creep and compression set
- Weatherability
- Vibration absorption
- Corrosion resistance
- Resistance to mold, mildew, and bacteria growth
- UL component recognition
- And more
Many different variations of LSR are available to support potential applications in a wide range of industries. To learn more about the specific properties of different liquid silicone rubber products, contact email tysales@tayanggroup.com.
